Bayesian learning, a statistical method, has been successfully applied to the feature combination stage of the evaluation function of the Othello program BILL, which won the 1989 North American Computer World Othello Championship. We have investigated the use of a novel neural network called HONEST in place of Bayesian learning in BILL. We implemented(More)
A 29-year-old healthy gentleman was diagnosed with ankylosing spondylitis (AS) and was treated with etanercept 50 mg subcutaneously weekly, after failing conservative treatment with non-steroidal anti-inflammatory drugs (NSAIDs) and exercise. Twenty months after initiation of etanercept, over the course of two weeks, he developed bilateral lower limb pain,(More)
The asymmetric unit of the title compound, 2C20H22N3O3(+)·SO4(2-)·H2O, contains four cations, two sulfate anions and two lattice water mol-ecules. One of the four cations shows a different conformation of the hy-droxy-ethyl group; the remaining three are all essentially superimposable. Two cations exhibit two-site orientational disorder [ratios = 0.524(More)
In the title compound, C(22)H(22)N(4)O(2)·0.25C(3)H(6)O, the disordered acetone mol-ecule lies with partial occupancy about the 2 axis. The mol-ecule of the malononitrile derivative is essentially planar excluding the methyl groups, with the largest deviation from the mean plane through the non-H atoms being 0.1955 (13) Å. Two rotamers with different(More)
